因此，我想获取一个声音文件并将其转换为数据包，然后将其发送到另一台计算机。我希望另一台计算机能够在数据包到达时播放它们。
我正在使用 AVAudioPlayer 尝试播放此数据包，但我找不到正确的方法来序列化 peer2 可以播放的 peer1 上的数据。
场景是，peer1 有一个音频文件，将音频文件拆分为许多小数据包，将它们放在一个 NSData 上并将它们发送给 peer2。对等方 2 接收数据包并在它们到达时一一播放。
有谁知道该怎么做？或者即使有可能？
编辑：
这是一些代码来说明我想要实现的目标。
// This code is part of the peer1, the one who sends the data
- (void)sendData
{
int packetId = 0;
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"myAudioFile" ofType:@"wav"];
NSData *soundData = [[NSData alloc] initWithContentsOfFile:soundFilePath];
NSMutableArray *arraySoundData = [[NSMutableArray alloc] init];
// Spliting the audio in 2 pieces
// This is only an illustration
// The idea is to split the data into multiple pieces
// dependin on the size of the file to be sent
NSRange soundRange;
soundRange.length = [soundData length]/2;
soundRange.location = 0;
[arraySoundData addObject:[soundData subdataWithRange:soundRange]];
soundRange.length = [soundData length]/2;
soundRange.location = [soundData length]/2;
[arraySoundData addObject:[soundData subdataWithRange:soundRange]];
for (int i=0; i<[arraySoundData count]; i++)
{
NSData *soundPacket = [arraySoundData objectAtIndex:i];
if(soundPacket == nil)
{
NSLog(@"soundData is nil");
return;
}
NSMutableData* message = [[NSMutableData alloc] init];
NSKeyedArchiver* archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:message];
[archiver encodeInt:packetId++ forKey:PACKET_ID];
[archiver encodeObject:soundPacket forKey:PACKET_SOUND_DATA];
[archiver finishEncoding];
NSError* error = nil;
[connectionManager sendMessage:message error:&error];
if (error) NSLog (@"send greeting failed: %@" , [error localizedDescription]);
[message release];
[archiver release];
}
[soundData release];
[arraySoundData release];
}
// This is the code on peer2 that would receive and play the piece of audio on each packet
- (void) receiveData:(NSData *)data
{
NSKeyedUnarchiver* unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
if ([unarchiver containsValueForKey:PACKET_ID])
NSLog(@"DECODED PACKET_ID: %i", [unarchiver decodeIntForKey:PACKET_ID]);
if ([unarchiver containsValueForKey:PACKET_SOUND_DATA])
{
NSLog(@"DECODED sound");
NSData *sound = (NSData *)[unarchiver decodeObjectForKey:PACKET_SOUND_DATA];
if (sound == nil)
{
NSLog(@"sound is nil!");
}
else
{
NSLog(@"sound is not nil!");
AVAudioPlayer *audioPlayer = [AVAudioPlayer alloc];
if ([audioPlayer initWithData:sound error:nil])
{
[audioPlayer prepareToPlay];
[audioPlayer play];
} else {
[audioPlayer release];
NSLog(@"Player couldn't load data");
}
}
}
[unarchiver release];
}
所以，这就是我想要实现的......所以，我真正需要知道的是如何创建数据包，以便 peer2 可以播放音频。
这将是一种流媒体。是的，现在我不担心接收或播放数据包的顺序......我只需要对声音进行切片，他们就可以播放每个片段，每个片段，而无需等待整个文件由 peer2 接收。
谢谢！
